I AM FKING INVINCIBLE
Anyways, the soundtrack is very cool, I really like the title soundtrack and the worm sountrack. The gameplay is fun. and the art looks really nice too.
Tho not sure how the rank b and rank d level works, its really hard to hit the boss and doesn't make as much money than the safe level. Also not sure if its a bug or not but you can see that I can fly to the sky while fighting worm. Its fun tho so its fine for me.
Overally, cool game!
